Thanks for the advice guys!
I started doing 5v5 today to get my 10 games for the week done. What can I say, ouch! An embarassment would be an understatment! even with a healer, we struggled to stay alive for more than 3 seconds each time! The mass of AOE and cc was confusing to say the least!
Anyway, I look forward to hopefully seeing some improvement in my performance with the accumulation of gear and hope it gets better.
